Overview on Viet Nam TV broadcasting TV digitization in Viet Nam Spectrum arrangement for DTV The Digital Dividend Summary
Overview on Viet Nam TV broadcasting
Viet Nam has 66 TV broadcasters:- 3 nationwide TV broadcasters
- 63 local TV broadcasters
- 109 TV free-to-air program channelsSo many local broadcasters! So many program channels! More difficult to allocate the available frequency channelsto deploy DTV services

1. Benefits of TV digitization for Broadcasters- Better quality of video and audio- More channels, more services (Mobile reception, mobileTV, HDTV, interactivity, data services)- Local TV broadcasters may have larger service coverage - DTV transmitter’s ERP requirement is lower- DTV gives a chance to set up SFN
TV digitization in Viet Nam
2. Benefits of TV digitization for telecommunications- Spectrum efficiency is high- Digital Dividend. That is a big chance to deploy more
radio broadband services;- The more Broadband services, the more multimedia
provided (such as Live TV channels, Interactive TV, Time-shifted TV, Video on demand...)

- DVB-T standard have been adopted by VTV since 2001 - VTC had launched DVB-T test project since 2002- 2005 DVB-T was adopted to deploy nationwide- Planning on radio television broadcasting transmission
to 2020 was adopted by Prime Minister in 2009;- Drafted Digitization Project on terrestrial TV was
submitted to Prime Minister for approval- Radio law and Telecommunications law
TV digitization in Viet Nam
Drafted Digitization Project on terrestrial:- The final target of DTV roadmap: 95% of
population served by digital TV.- Transmission standard: DVB-T and its next
versions; - Compression standard: MPEG-2, MPEG-4 part
10/ H.264 (after 2014: MPEG-4 part 10 /H.264 is mandatory)
- Analog switch off has been scheduled from 2015 to the end of 2020 (region by region)

DTV roadmapTV digitization in Viet Nam
* Terrestrial DTV- VTC has launched DTV services since 2006,
+2 MUX using MPEG-2 compression standard, + more than 20 TV program channels; - AVG has a trial of DTV SFNs with 3 MUX using MPEG-
4 compression standard in Ha Noi and Ho Chi Minh City;
- More than 2 million set-top-box have been sold out to market
TV digitization in Viet Nam
* Mobile TV- DVB-H was tested by VTC corporation in 2006,- T-DMB trial project has been broadcasted by VTV
in Ha Noi and Ho Chi Minh city
* DTH- VTV launched DTH using DVB-S standard since 2004- VTC launched DTH using DVB-S2 standard since 2009
TV digitalization in Viet Nam
Spectrum arrangement forterrestrial TV
1. Multiplex and network planning- 3 nationwide broadcasting transmission operators
with 7 DTV Multiplexes- 5 – 7 DTV MUX for existing local ATV (multiplex by
regional areas)
Spectrum arrangement forterrestrial TV
2. Frequency channel allotment for DTV- to broadcast 2 MUX for VTV and 2 MUX for VTC with
nationwide coverage using MFN; - to broadcast 3 MUX for third nationwide operator
using SFN providing Pay TV services;- to broadcast 1 MUX for each regional networks
delivering existing local TV channels
Spectrum arrangement for terrestrial TV
3. Frequency bands- VHF band III: 174 – 230 MHz- UHF band:
Before 12/2009 : 470 – 806 MHz After 12/2009: 470 – 790 MHz
4. Draft of VHF band plan- To be planned for DTV, Digital radio, Mobile TV- Band III VHF (174-206) MHz for DVB-T/T-DMB- Band III VHF (206-230) MHz for T-DMB/T-DAB
Spectrum arrangement for terrestrial TV
5. Draft of UHF band plan- Mainly for DTV implementation- UHF (470-694 MHz) for DTV Long-term usage- UHF (694-790 MHz) for DTV/ATV temporary
usage and to be freed up to develop other radio services (Digital Dividend)
- After 12/2020 UHF band 694 – 790 MHz is going to be freed up to launch other radio broadband services
• Digital Dividend is the spectrum made available over
and above that required to accommodate the existing analogue television services in a digital form in VHF and UHF
